This is a non-provisional application that claims benefit to U.S. Provisional Patent Application Ser. No. 63/175,353 filed 15 Apr. 2021, which is herein incorporated by reference in its entirety.

FIELD

The present disclosure generally relates to lacing systems for sporting shoes, and in particular, to a system and associated method for a dial cover for a rotary closure lacing system.

BACKGROUND

Among athletic shoe lacing systems, especially rotary closures, many users report having trouble gripping and turning the dial of the rotary closure to tighten the lacing or unlock the tightened lacing. Previous examples have introduced grippable materials onto the surface of the dial; however, many users still find the small size of the dial and stickiness of permanent gripping structures to be cumbersome and difficult to keep clean. Further, some level of customizability and interchangeability is often demanded from users due to sports and other organizational affiliations.

It is with these observations in mind, among others, that various aspects of the present disclosure were conceived and developed.

Referring to the drawings, embodiments of a dial cover configured for engagement with the dial of a rotary closure are illustrated and generally indicated as 100, 200, 300 and 400 in FIGS. 1-24B.

FIGS. 1-9 illustrate a first embodiment of a dial cover 100 configured to encapsulate a dial 11 of a rotary closure 10 for improved gripping of the surface of the dial 11 during winding and release of the rotary closure 10. In particular, as shown in FIGS. 1-3, the dial cover 100 is configured for removable engagement with the dial 11 and conforms to a shape of the dial 11, particularly a top surface 12 and a peripheral edge 13 of the dial 11. In one embodiment, the dial cover 100 is configured to encapsulate the peripheral edge 13 of the dial 11 such that a shape of the peripheral edge 13, including a plurality of gripping recesses 14 and gripping ridges 15 (FIGS. 8 and 9), is assumed by the dial cover 100. Referring to FIGS. 4-7, the dial cover 100 includes a body 101 that defines an outer convex surface 103 that provides a gripping surface to a user, and an inner concave surface 107 defined interior to the outer convex surface 103 that encapsulates the dial 11. In some embodiments, the body 101 further includes an aperture 104 defined through a center of the dial cover 100. In some embodiments, the inner concave surface 107 defines an inner lip 106 along a bottom of the sidewall portion 130 that extends inward towards a center of the dial cover 100 to secure the dial cover 100 underneath the peripheral edge 13 (FIG. 3) of the dial 11. The dial cover 100 defines a topside portion 120 and a sidewall portion 130, where the sidewall portion 130 is configured to conform to the peripheral edge 13 of the dial 11. In a primary embodiment, the dial cover 100 can be made of a flexible material such as rubber, silicon, a thermoplastic elastomer material (TPE), a thermoplastic polyurethane material (TPU) or another suitable material with a suitable friction coefficient for gripping. Engagement of the dial cover 100 with an alternative dial 21 is illustrated in FIGS. 10 and 11.

FIGS. 12-15B illustrate a second embodiment of the dial cover 200 that includes one or more protrusions 209 that provide a surface to aid the user in gripping and rotation of the dial 11 when the dial cover 200 is coupled with the dial 11, with sub-variations of protrusions 209 being respectively illustrated as 209A, 209B and 209C in FIGS. 13A-13C, 14A-14C and 15A and 15B. FIGS. 16-21B illustrate a third embodiment of the dial cover 300 that accommodates a token 318, where the token 318 can include a logo or other personalized indicia visible through an aperture 304 of the dial cover 300. FIGS. 22-24B illustrate a fourth embodiment of the dial cover 400 that is a rigid piece rather than a flexible material and configured for coupling with the alternate embodiment of the dial 21 (from FIG. 11) in a snap-fit engagement.

In one method of assembly of the dial cover 100 (or 200, 300 or 400), the dial cover 100 is stretched over or otherwise snapped onto the dial 11 (or 21) such that the inner concave surface 107 of the dial cover 100 encapsulates the peripheral edge 13 and at least part of the top surface 12 of the dial 11. In some embodiments, the inner lip 106 of the dial cover 100 couples underneath the peripheral edge 13 of the dial 11. In another aspect, the sidewall portion 130 of the dial cover 100 engages the peripheral edge 13 of the dial 11 through friction. In another embodiment shown in FIGS. 24A and 24B, the dial cover 400 engages an underside of the ridgeless peripheral edge 23 of the dial 21 by a plurality of tangs 406 of the dial cover 400 that couple with the dial 21 in a snap-fit engagement.

Once assembled, the inner concave surface 107 of the dial cover 100 conforms to the peripheral edge 13 of the dial 11 and provides a gripping surface not only for the inner concave surface 107 of the dial cover 100 to grip the dial 11 for rotation, but to allow a user to better grip the outer convex surface 103 of the dial cover 100 and rotate the dial 11 in a clockwise or counterclockwise rotational direction. In the embodiments of the dial cover 100 (and 200 and 300) of FIGS. 2, 12 and 16, the dial cover 100 includes a flexible material and couples with the peripheral edge 13 of the dial 11 such that the dial cover 100 conforms to a plurality of recesses 14 and ridges 15 of the peripheral edge 13 of the dial 11. In contrast, in the embodiment of the dial cover 100 with the dial 21 of FIGS. 10 and 11, the dial 21 features a ridgeless peripheral edge 24 that the dial cover 100 conforms to. An assembled view of a rotary closure 10 including the dial cover 100 engaged with the dial 11 is illustrated in FIG. 1.
